motor vehicles, one of the-objects being to produce a radiator having water tubes which are so constructed and arranged that they can be easily and-quickly cooled by the action of an air current passing through the radiator. a

Another object is to produce a simple radiator structure the elements of which are accessible for the purpose of making repairs, and also for the purpose of removin scale or other matter from the interior 0 the water conductors.

A further object is to provide an improved means for controlling the circulation of water through the radiator.

Figure I is a front elevation of a radiator embodying the features. of our invention. Fig ll isan enlarged fragmentary side elevation, showing the parts near the lower end'of the radiator. Fig 111 is an enlarged horizontal section. taken on the line TIL- Ill, Fig I. Fig. IV is any enlarged vertical section, partly broken away, taken-approximately on the line lVlV, Fig. ,1. Fig. V is a section taken approximately on the line VV,"Fig. VI. Fig. V1 is a vertical section taken approximately through the middle of the radiator. v

The radiator we have shown to illustrate the preferred form of our invention comprises an upper compartment A having an inlet opening 1, an upper manifold B arranged immediately below said upper compartment and provided with an inlet port for the admission of water from said compartment, see. Fig. V1. The uppercompartment A comprises a top wall 1, inclined side walls5, a front wall 6. and a rear wall 7. The. upper manifold B comprises an upper member 8, in the form of an inverted trough, arranged between and secured to the walls of the upper compartment A. The lower half of the manifold B is a trough shaped member 9, flanged outwardly at its upper edge and secured to the manifold member 8.

of vertical water tubes 12. The manifolds B and C are also connected by vertical channel shaped members 13 arranged at the sides of the radiator, as shown most clearly in Figs HI and VI. 1

14: designates a discharge pipe leading from the lower manifold C. I Partition members 15 divide the upper manifold B into a plurality of compartments, and the lower manifold C is divided by partition members 16.

The waterenters the radiator at the port 1 near the upper end of the chamber A, see Fig. VI, circulates through this chamber and then flows through-the port 3 to a. compartment 17 of the upper manifold B. By arranging the partition members 15 in the upper manifold B, I provide the compartment 17, just referred to, and also pro vide compartments 18 and 19. These dif ferent compartments 17, 18 and 19 have no direct communication with each other, and the water entering the compartment lif can only escape. by flowing downwardly through the vertical tubes which communicate with said compartment 17. Water flowing downwardly from the last mentioned compar ment passes through certain tubes 12 and enters a compartment 17 in the lower manifold. It will be noted that the water is free to flow upwardly from the compartment 17'to the compartment 18 of the upper manifold, and then downwardly through certain tubes 12 to the compartment 18 of the lower manifold. Thereafter the water circulates upwardly through certain water tubes, flows into the compartment 19 of the upper manifold. and then flows downwardly into the compartment 19' of the lower mani-' A lower manifold G is connected to the upper manifold B by means must circulate through all of the different current, as is well understood in this art.

' 20 designates air tubes extending through the upper chamber A and secured to the front and rear walls of said chamber. The object in arranging the air tubes at this point is to permit-air to circulate through the upperv portion of the radiator, thereby cooling the Water to a certain extent before it entersthe upper manifold B.

To insure a most effective cooling action, the blade-shaped water tubes 12 are preferably flattened, and the side Walls of each tube preferably converge from its very narrow rear edge toward the front of the radiator, as shown most clearly in Fig. III. By flattening the tubes in this manner and arranging them as shown in Fig. 111, a

very large area of the surface of each tube is exposed to the current of air which circulates between the tubes. The water tubes 12 are preferably arranged in two rows the tubes of each row being in a plane between the tubes of the other row so that each tube is exposed to the air passing through the radiator.

21 designates a screen arranged in front of the water tubes 12 to prevent dirt, leaves and' other matter from passing into or through the radiator at this point. 22 designates a similar screen arranged in front of the air tubes 20. The screen 21 is preferably fastened to the frame 23, the latter being detachably secured to the radiator so that it may be readily removed when it becomes necessary to repair the tubes 12 or to stop leakage by applying solder at the junction of a tube and a manifold.

1 24 designates drain cocks secured to the lower manifold C to permit the drainage of water from/the compartments 17, 18' and 19.

The lower manifold C is a sectional structure consisting of an upper section 24 in the form of an inverted trough having outturned flanges 25 at its lower edge (Fig. IV). The lower section 26 is a trough shaped member having outturned flanges 27 at its upper edge. These flanges 25 and 27 extend around the trough shaped members and lie close to each other as shown in Fig. IV. 28 designates packing arranged between flanges and 27. The means for securing the manifold sections to each other comprises a pair of bars 30 arranged on opposite sides of the radiator-,each of said bars being'provided with a longitudinal groove 31 for the reception of flanges and '27. The walls of the grooves 31 are preferably inclined, Fig. TV, and the flanges 25 and 27 grooves 31.

'the introduction of water are preferably provided with inclined members 32 which engage the walls of said The-inclined members 32 are preferably wedge shaped elements soldered or otherwise secured to the flanges 25and The grooved bars 30 are connected to each other at their ends-by means of bolts 35, passing through the ends of said bars, Fig. III, and provided with nuts 36 which may be adjusted to force the bars toward each other. When the bars 30 are securely.

connected by the bolts 35, the flanges 25 and 27 of the manifold sections are forced toward each other to prevent leakage at the junction of these manifold sections.

Obviously, the -lower manifold section may be very easily and quickly removed by merely removing the nuts 36 from the bolts and then releasing the bars 30'from the manifold. This is quite important for the reason that it permits the user to clean all of the long vertical water tubes 12 by merely removing the lower half of the manifold C, and then inserting a suitable cleaning tool into the tubes.

Since all of the tubes are exposed when the lower section of manifold C is removed,

the radiator may be cleaned very quickly and thoroughly.

Another advantage is that the sediment which accumulates in the lower portion of the radiator may be easily removed from the detachable lower section of the manifold C.

+0 designates lugs secured to the bottom wall of the lower manifold and adapted to be secured to a part of the motor vehicle by bolts 41, shown in I.

42 designates the usual filling tube secured to the upper end of the radiator to permit into. the system.

A radiator comprising water conductors including a manifold having two sections, and means for uniting said sections, said means including a pair of fastening devices arranged on opposite sides of the manifold and means for connecting said fastening devices to secure them to the manifold.

2. A radiator comprising water conductors including a manifold comprising sections each of which is provided with a pair of outturned flanges, fastening devices arranger-l on opposite sides of said manifold, said fastening devices being groovedto receive said flanges, andineans for connecting said fastening devices to secure said manifold sections to each other.
